Terms and Conditions

Version 1.0 · Effective 25 August 2026

These Terms govern the download and use of macPST. macPST is an independent private hobby project, provided by Philipp Johann Fritz in his personal capacity.

1. Provider and nature of the project

macPST (the “Software”) is an independent, private, non-commercial hobby project created and provided by Philipp Johann Fritz, Gartenstraße 49, 7552 Stinatz, Austria (the “Licensor”). The Licensor acts solely in his personal capacity. No employer, company, business, client, affiliate or other organisation associated with the Licensor is a party to these Terms or assumes any obligation, warranty, support commitment or liability relating to the Software.

2. Acceptance and scope

By installing, launching, accessing, copying or using the Software, selecting the download confirmation above, or selecting “Accept and Continue” in the Software, you agree to these Terms. If you accept on behalf of an organisation, you confirm that you are authorised to bind that organisation. If you do not agree, do not download or use the Software and delete all copies in your possession. These Terms govern the proprietary parts of the Software. Third-party components remain governed by their respective licences.

3. Limited licence

Subject to these Terms, the Licensor grants you a limited, non-exclusive, non-transferable, non-sublicensable licence to install and use the version of the Software supplied to you for your own private purposes or your organisation’s internal purposes. You may make a reasonable number of backup copies solely for that permitted use.

Except where mandatory law or an applicable third-party licence expressly permits it, you may not sell, rent, lease, sublicense, redistribute, make available to third parties, commercially exploit, modify, adapt, translate, reverse engineer, decompile, disassemble or attempt to derive source code from the Software. No ownership or intellectual-property right is transferred to you.

4. Reservation of rights and future commercial terms

All rights not expressly granted are reserved by the Licensor. The current availability of a version free of charge does not create any entitlement to continued free availability, future versions, updates, upgrades, additional functionality, maintenance, support or services. The Licensor may discontinue the Software or offer future versions, features, updates, maintenance, support or other services only under new or additional terms and may charge fees for them. Any fee or new restriction applies prospectively and does not retroactively alter a licence already granted for an existing version, unless you expressly agree otherwise.

5. Intended use and limitations

The Software is a read-only viewer intended to display information from Microsoft Outlook PST files. It is not an archive, backup, recovery, migration, forensic, e-discovery, records-management, security or compliance system. It must not be used as the sole basis for legal, regulatory, employment, financial, operational or other important decisions. The Software may fail to open a file or may display, decode, search, order or export information incompletely or incorrectly. Password-protected, damaged, unusual or unsupported PST files and individual message properties may not work.

6. Your responsibilities

You are solely responsible for ensuring that you have the right to access and process every PST file and its contents; for compliance with privacy, confidentiality, employment, intellectual-property, retention and other applicable laws; for maintaining complete, current and independently restorable backups before use; for using copies rather than original archives where appropriate; for verifying all displayed or exported results against the source and by other suitable means; and for scanning attachments and exported files before opening them. You assume all risks arising from your files, attachments, configuration and use of the Software.

7. No warranty or service commitment

The Software is provided voluntarily, free of charge and “as is” and “as available”, without any promise regarding quality, accuracy, completeness, reliability, security, fitness for a particular purpose, compatibility, availability or freedom from errors or third-party rights. The Licensor does not promise maintenance, support, updates, security fixes, data recovery, response times, service levels or continued availability. To the fullest extent permitted by law, statutory warranty and guarantee claims are excluded. Mandatory statutory rights remain unaffected.

8. Limitation of liability

To the fullest extent permitted by applicable law, the Licensor is not liable for damage caused by slight negligence. In particular, the Licensor is not liable for indirect, incidental, special or consequential loss; loss of or damage to data; loss of profit, revenue, savings, business, opportunity or goodwill; business interruption; costs of replacement software, recovery, reconstruction or investigation; or claims by third parties.

Where liability for gross negligence may legally be limited, it is limited to direct damage that was typical and reasonably foreseeable when these Terms were accepted and, in aggregate, to EUR 100. If a monetary cap is invalid in a particular case, liability remains limited to the lowest amount permitted by law. You must take reasonable steps to prevent and reduce damage, including maintaining and testing backups.

Nothing in these Terms excludes or limits liability for intentional conduct, culpably caused personal injury, liability under mandatory product-liability law or any other liability that cannot lawfully be excluded or limited. Any exclusion or limitation also applies to the Licensor’s representatives and assistants.

9. Updates and changes

You decide whether to install an update. An update may change, remove or add functionality and may require acceptance of new terms. The terms accepted for an existing version continue to govern that version. The Licensor may change these Terms only prospectively; material changes for a version you already use require your acceptance where required by law.

10. Third-party software

The Software includes libpff and may include other third-party components. Their copyright notices and licence terms are available under “Acknowledgements” in the Software. Nothing in these Terms restricts rights granted directly by a third-party licence. In the event of a conflict regarding a third-party component, that component’s licence prevails.

11. Privacy

PST content is processed locally on your device. Details about local preferences, optional update checks, the website and contact requests are described in the Privacy Policy.

12. Termination

This licence terminates automatically if you materially breach these Terms. Upon termination, you must stop using and delete the proprietary parts of the Software, without prejudice to rights under applicable third-party licences. Provisions concerning ownership, disclaimers, liability, governing law and other provisions intended by their nature to survive remain in effect.

13. Governing law and jurisdiction

These Terms are governed by Austrian law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. To the extent legally permissible, the courts having subject-matter jurisdiction at the Licensor’s place of residence have exclusive jurisdiction. Mandatory consumer-protection rules and mandatory jurisdiction rules remain unaffected.

14. General provisions

These Terms constitute the entire agreement concerning the free version of the Software unless a separate written agreement expressly supersedes them. Failure to enforce a provision is not a waiver. You may not assign these Terms without the Licensor’s prior written consent. The Licensor may transfer the Software, associated intellectual-property rights and these Terms to a legal successor or to an entity established or controlled by him, provided your existing licence is not materially reduced. If a provision is invalid or unenforceable, the remaining provisions remain effective; the invalid provision is replaced only to the extent legally permissible by the applicable statutory rule.
